Unbound faild after upgrade.

[nv.nguyen]

My proxmox gateway Ver 7.3-11. After upgrade unbound (unbound/oldstable-security 1.13.1-1+deb11u2 amd64 [upgradable from: 1.13.1-1+deb11u1]), Unbound cannot start.

systemctl start  unbound.service
Job for unbound.service failed because the control process exited with error code.
See "systemctl status unbound.service" and "journalctl -xe" for details.

unbound -d -vvvv

Is something else listening on the relevant ports?
but it seems more likely related to a permission issue - and nothing in the changelog between those two version indicate that something changed w.r.t. permissions....

- please share the journal output and the systemctl status output

I have add this config in /etc/unbound/unbound.conf

server:
    # Enable Unbound to work with IPv4
    do-ip4: yes

    # Disable IPv6 if not needed
    do-ip6: no

    # Define the interfaces to listen on
    interface: 0.0.0.0
    interface: 127.0.0.1

Unbound allready running.
